Method and Device for Orienting Wound Dough Products Along a Decelerating Section

Abstract

A method for orienting wound dough products in a defined end position by winding a triangular or trapezoidal dough piece along a winding section includes winding from the base of the dough piece with the narrower end of the dough piece forming an end protruding outside at the circumference of the dough product. The end position of the dough product is defined by a position of the end protruding at the outside. The wound dough product is decelerated from a translational starting speed to a translational end speed along a decelerating section. The resulting deceleration torque is used as a driving torque for a rolling movement of the dough product. The rolling movement is stopped by resistance when the end of the dough product is in contact with the surface. The translational conveying speed and/or the speed of rotation of the wound dough product is changed in control section.

1 . A method for orienting wound dough products in a defined end position, the dough product being produced by winding a triangular or trapezoidal dough piece along a winding section, and the dough product being wound starting from the base of the dough piece, and the narrower end of the dough piece forming an end protruding outside at the circumference of the dough product, and the end position of the dough product being defined by a specific position of the end protruding at the outside, and the wound dough product being decelerated from a translational starting speed to a translational end speed along a decelerating section, and the resulting deceleration torque being used as a driving torque for a rolling movement of the dough product so as to cause the dough product to roll on a surface, the sense of rotation of the rolling movement of the dough product corresponding to the winding direction from the inside to the outside of the wound dough product, and the rolling movement being stopped by the rolling resistance caused by the end when the defined end position, in which the end of the dough product is in contact with the surface, is reached, wherein
 the wound dough product passes through a control section between the end of the winding section and the start of the deceleration section, the translational conveying speed of the wound dough product and/or the speed of rotation of the wound dough product being changed in the control section. 
 
     
     
         2 . The method according to  claim 1 , wherein
 the translational conveying speed of the wound dough product and/or the speed of rotation of the wound dough product are set to a predefined target value in the control section.   
     
     
         3 . The method according to  claim 1 , wherein
 the speed of rotation of the wound dough product is decelerated in the control section.   
     
     
         4 . The method according to  claim 3 , wherein
 the speed of rotation of the wound dough product is decelerated to zero in the control section.   
     
     
         5 . The method according to  claim 3 , wherein
 the speed of rotation of the wound dough product is reversed in the opposite direction in the control section, the rotating movement in the opposite direction corresponding to the rotating movement during deceleration in the decelerating section.   
     
     
         6 . The method according to any one of  claim 1 , wherein
 in the decelerating section, the wound dough product is decelerated by being transferred from a first conveyor band, which is driven to circulate at a first conveying speed, to a second conveyor band, which is driven to circulate at a second conveying speed, whereby the desired rolling movement is imparted to the wound dough product.   
     
     
         7 . The method according to  claim 6 , wherein in the decelerating section, the wound dough product is displaced vertically downward when being transferred from the first conveyor band to the second conveyor band. 
     
     
         8 . A device for carrying out a method for orienting wound dough products in a defined end position, the device comprising a winding section in which dough pieces are wound to form dough products and a decelerating section in which the dough products are decelerated in a defined end position, wherein
 the device has a conveyor for forming a control section between the winding section and the decelerating section, the translational conveying speed of the wound dough product and/or the speed of rotation of the wound dough product being changeable in the control sectiones between the winding section and the decelerating section using the conveyor.   
     
     
         9 . The device according to  claim 8 , wherein
 the conveyor between the winding section and the decelerating section is formed by two conveyor bands which are driven to circulate, the first conveyor band engaging the wound dough products from below and the second conveyor band engaging the wound dough products from above, and the translational conveying speed of the wound dough product and/or the speed of rotation of the wound dough product being changeable by adjusting the speed of circulation of the first conveyor band and/or by adjusting the speed of circulation of the second conveyor band.   
     
     
         10 . The device according to  claim 9 , wherein
 the speed of circulation of the first conveyor band and the speed of circulation of the second conveyor band can be adjusted independently of each other.   
     
     
         11 . The device according to  claim 9 , wherein
 the upper conveyor band of the conveyor consists of at least two spaced-apart conveyor belts, each of the two conveyor belts coming into contact with the dough product eccentrically.   
     
     
         12 . The device according to  claim 8 , wherein
 to form the decelerating section, a conveyor band having a lower conveying speed is disposed downstream of the lower conveyor band of the control section, the wound dough products being decelerated owing to the difference between the conveying speeds when being transferred from the lower conveyor band of the control sectiones to the conveyor band of the decelerating section disposed downstream of said lower conveyor band, whereby the desired rolling movement is imparted to the wound dough products.   
     
     
         13 . The device according to  claim 8 , wherein
 a downward vertical height difference is provided between the lower conveyor band of the control section and conveyor band of the decelerating section disposed downstream of said lower conveyor band.
